Former U.S. Vice President Dick Cheney has criticized Russia's alleged interference in the U.S. presidential election, calling it a hostile act.

Cheney said Russian President Vladimir Putin had made a serious attempt to interfere in the 2016 election and other democratic processes in America.

In a speech at a speaker's conference in New Delhi, Cheney said, "In some quarters, that would be considered an act of war."

Cheney's accusation comes at a time when both the U.S. Senate and House of Representatives intelligence committees are investigating possible Russian interference in the election that brought President Donald Trump to power.
